TIRE.

To all '1o/0m t may concern Be it known that I, ManonLmNo Toso, asubject of the King of Italy, residing at San Bruno, in the county ofSan Mateo and State of California, have invented new and usefulImprovements in Tires, of which the following is a specification.

This invention relates to vehicle tires, and

pneumatic tire and protecting means therefor.

The object of" the presentinv'ention is to provide a ver-y substantial,durable and practical pneumatic tire involving a body portion adapted tobe inflated and which is surrounded by a removable belt or armor formedof a plurality of interchangeable, removable and renewable links; and toprovide a wearing surface formed of a plurality of projecting pinsadapted to contact with and engage the roadbed to aid in the traction ofthe tire.

The invention consists of the parts and the construction and combinationof parts, as hereinaftelr more fully described and claimed, havingreference to theaccompanying drawings, in which- Figure l is atransverse section through the tire. Fig. Qis a partial longitudinalsection through the tire. Fig. 3 is a plan view of a portion of thetire.

he present embodiment of my invention comprises an inflatable inner tube2 surrounded by a suitable form of casing R, which may bevmade offabric, or'rubber, or

separable clencher edges el for engagement with suitable rims of thevehicle wheel. The upper portion of the tire casing 3 is built up with aconsiderable thickness ot Specification of Letters Patent. Applicationined August 2s,

rubber or other appropriate material at 5, having substantially straightside surfaces 6 which terminate Aon each side of the tire in concaveddepressions 7; the extreme periphery of the casing-being formedsubstantially flat, as indicated at 8. The periphery of the casing isshown as encompassed in an annular fabric orother suitable material,forming a belt .'9 and having ring-like cushion members l0 on each sideof the tire which are snugly embraced in tubular flanges formed integralwith the belt body 9. 'At suitable intervals on the exterior of the belt9 of the tire there is provided a series of spurs or projections 11,whichv extend transversely across the tire cushion 5 and which PatentedSept.. 10, 1912. 1911. serial No. 646,569.

are lilledwith a sot't or resilient material, as rubber, at ll,whichcushion sections 1l are inclosed in the Afabric walls 12foi-medintegral with the body of the belt 9.

The tread or road-engaging portion of the tire is composed of acontinuous, flexible, endless band formed of a number of metallic orother suitable links 13 extending periph-- erally around the tire andhaving suitableI hinge-like joints secured flexibly by a pivot member.lll-,- the outer ends of which are so cui-ely fastened to preventlongitudinal movement, as by riveting or otherwise. The links 13 may bemade ot suitable length and width to give the deqfred exterior orinterior contour to produce the most advantageous results; as shown inFig. l, the transverse contour of the links 13 issuch as to be somewhatconvex, and from the convex surface of the several links there projectsa number of removable traction pins, or equivalent devices, l5, theheads of which are of such proportion to form an almost continuoustraction surface for the tire. The innerends of the. traction pins l5may be tapered, as at 1G, so as to be driven firmly into suitableopenings 17 formed lor their reception in the chain links or plugs lfl.Each of the links 13 is concaved on its under surface, so as to receivethe projecting portions l2 of the belt 9 of the tire, and thereby allcircumferential or transverse slippage or movement ofthe chain member ispositively prevented relative to the main portion of the'tire. Thewearing` pins l5 may be secured in place by screwing or ,herwise, asdesired, but by n" 'the portions 1G with a slight taper they are readilydriven out. of the plugs .13 when the head portions 15 have. been worndown.

The'tire portion 3 may be made substan tially solid, if desired, and theinflatable tube omitted, but. it is advantagcolisy to have thetransverse width of the chain links lil equal to or slightly greaterthan the width of the cushioning body 5, so as to protect the` latterfrom abrasion with gravel :or projections in the roadway.

Having thus described my invention, what I claim and desire to sccurebyLetters Paent isl. A tire comprising asuitabljr shaped body pirtionhaving coni-avril ('lepressions at the'sides near the periplnfry, anannular fabric of belt-like form micompassing the i periphery Iof saidbody and fashioned with tending across the same.

v2. A tire comprising a suitably shaped body portionhavingv Iconcaveddepressions ,at the sides near theperiphery, an annular y fabric ofbelt-like form encompassing the periphery of said' body and fashionedWith tubular flanges at the side edges, and-ringlike cushion membersinclosed bythe t'ubularflanges of said belt, and fitting said con "payeddepressions, said belt having spaced projections on its outer surfacecxtendin 'across thesarne, and having spacedyfabric uWalls to inclosethe projections.

' f 3.v A tire comprising' a .suitably shaped body portion havingconcaved depressions at jthe sides near 'the periphery, an annular'fabric of belt-like form encompassing the periphery'of said body andfashioned with tubular anges at the side edges, and ringlike cushionmembers inclosed by the tubular flanges of said belt, and fitting saidconcaved depressions, said belt hav-lng spaced projections on its outersurface extending across the same and having spaced fabric Walls toinclose the projections, and a' link belt encompassing the fabric belt`the uni der-surfaces of the links of said belt being concaved -andinclosing said cushion members.

In testimony whereof I have hereunto set MARCELLINO T080. Witnesses JOHNH.HERR1NG,
